Funnily enough, there are people who either supplement their living expenses or entirely earn their living expenses by selling EVE currency for real money. The actual number of people who do this is disputed, but it's been a well known fact among EVE players for a long time. So, in a way, their real-world bread is on the line if EVE changes significantly enough to destroy their source of income. It's a weird situation.
That which pays thy bills is the real world.
It can correspond to another statement: that which feeds thy mouth is the real world, too.
I can't eat virtual bread. It's not the real world.
